Solution 2:

Use iTunes to Go Back to the Old iOS

Since you can upgrade your iOS from the iTunes app on your computer, you can also perform an iOS 17 downgrade with iTunes. But it has its cons. For instance, you might lose the existing data on your phone as it would restore your device to its factory settings. The process is also a bit technical, and you might end up damaging your device in the process.

What You Need:

· Download the IPSW file to your computer.
find my iphone
choose ipsw
trust computer
restore iphone
download file
restore to ios 16

Steps to Downgrade iOS 17 Using iTunes:

1. From your iOS device go to "Settings" > "[Your name]" > "Find my" > "Find My [device] " > Disable "Find My [device] ".

2. Get an iOS version you want from IPSW.me and download the IPSW file to your computer.

3. Then connect your iOS device to the computer and click "Trust" in the "Trust This Computer?".

4. Select your iOS device in iTunes. Then, go to its "Summary" tab and hold the Shift key in Windows or the Alt/Option key in Mac as you click the "Restore" Button.

5. Select the IPSW file you downloaded and click "Open".

6. Click Restore to confirm. Wait for a while and let iTunes complete the iOS 17 downgrade.

Note:
If you're using a Mac with macOS Catalina or later, open a new Finder window to access your iPhone/ iPad instead of iTunes. Click on Trust and then proceed with the same steps above.

Solution 3:

Downgrade From iOS 17 Beta to iOS 16

If you've previously installed the iOS 17 Beta or iPadOS 17 Beta through Apple's Developer Program or Software Beta Program, you'll need to follow the specific steps below to safely revert to a public iOS version.

1. Connect your iPhone/iPad to the computer using a Lightning cable.

2. Launch iTunes on your PC, or Finder on your Mac.

3. Put your iPhone/iPad in Recovery Mode. The methods vary on different devices.

4. Click Restore on the popup window to restore your device and install the latest public iOS/iPadOS version.

5. Wait until the process is complete. This will wipe all data on your device.

2. Downgrade iOS to a Version No Longer Signed by Apple

know, the entire process of downgrading an iOS version is time-sensitive. If you have passed the downgrade validity period but still want to downgrade to a version no longer signed by Apple, then you need to use a third-party tool. By taking the assistance of tools like TinyUmbrella, FutureRestore and TaigOne Downgrader, you can install any supported iOS version on the device. They mimic Apple's signature, letting us install personalized firmware (iOS version) on iDevices.

Note:
The entire process would be pretty technical, and it might not yield positive results. Since these third-party tools are not supported by Apple, you need to jailbreak your device to do it. This is not recommended as it will affect the warranty of your device, and you would no longer have access to the official iOS releases as well. Furthermore, it will make your device vulnerable to unwanted security threats.

FAQs About iOS 17 Downgrade

Yes, you can downgrade iOS to a previous version signed by Apple. If you have upgraded your device to a version, you can easily downgrade to a stable version about a week or two after a new release.
There are many ways to undo an iOS 17 update on an iPhone. If you want, you can take the assistance of iTunes or Dr.Fone - System Repair (iOS) to do the same. If you have a jailbroken device, you can even give tools like TinyUmbrella a go.
Ideally, you can't downgrade your device to an unsigned iOS version. This is because the Apple server won't authenticate your downloading request without a valid SHSH blob. That is why users take the assistance of a previously saved SHSH blob to do the same. You can also use a third-party downgrading tool to do it as well.
When we install an iOS version on the device, the Apple server asks for a digital signature to authenticate it. A signed IPSW file would have a verified signature issued by Apple, letting us upgrade/downgrade the device without any hassle. Therefore, if an IPSW file is not signed by Apple, then it will not be recognized by the server, and the upgrading/downgrading process won't be completed.
The Apple Software Program lets us test the releases of iOS before the public availability. You can join or leave the program anytime you want without spending anything. If you want to leave it, then go to the Unenroll section of the website.
After downgrading an iOS update, you might find an existing software profile on your device storage. To remove this, just go to your device's Settings > General > Profile and select the iOS profile from here. Tap on the "Delete Profile" option and confirm your choice to remove it.
Both SHSH and SHSH2 blobs are referred to as digital signatures deployed by Apple on respective IPSW files. This protects the authenticity of the IPSW files, and only signed software would be installed on the device. When Apple releases a new iOS version, it stops signing the previous version. In this way, users need to upgrade to the latest public iOS version. This is where previously saved SHSH blobs are used to forge these signatures in order to downgrade our devices.
You can restore a previously stored SHSH blob from your device or forge Apple's signature. There are a few third-party tools like FutureRestore that can help you do the same. You can also choose to dump your SHSH blobs in order to use them afterward. Though, in most cases, users have to jailbreak their iOS device in order to do it.
